## CLI and manual documentation
The SYNOPSIS and OPTIONS sections of the manual pages are generated from the
literal `getopt_long` declarations in `src/{local,server,tunnel,redir,manager}.c`
and the `getopts` declaration in `src/ss-nat`. Descriptions and argument names live
in `CLI_DOC` source comments: common C options in `src/utils.c`, program-specific
overrides in the corresponding C file, and shell options in `src/ss-nat`.
Each entry has an AsciiDoc term such as `--mtu <MTU>::` followed by its description.
The generator checks option coverage and argument arity across platform variants;
describe platform or feature restrictions in the comment. Cipher lists come from
the C cipher tables. Keep explanatory sections and examples in `doc/*.asciidoc`.
After changing a parser or its documentation comments, regenerate the checked-in
pages and run the generator tests:
```sh
python3 scripts/gen_cli_docs.py
python3 scripts/gen_cli_docs.py --check
python3 -m unittest discover -s tests -p test_gen_cli_docs.py
```
To render the manuals, install Python 3, AsciiDoc, and xmlto, then run:
```sh
cmake -S . -B build-docs -DWITH_DOC_MAN=ON -DWITH_DOC_HTML=ON
cmake --build build-docs --target doc-man doc-html --parallel
```
The build generates pages in the build directory without modifying source files
or executing target binaries, so it also works when cross-compiling. CI checks
that committed pages are current and renders both man and HTML output.

Not available in manager mode.
`ss-redir`(1)::
See this command's generated SYNOPSIS and OPTIONS for its accepted arguments.
-m <encrypt_method>::
Set the cipher.

*shadowsocks-c* accepts 22 different ciphers:
+
2022-blake3-aes-128-gcm, 2022-blake3-aes-256-gcm,
2022-blake3-chacha20-poly1305,

chacha20-ietf-poly1305, xchacha20-ietf-poly1305,
salsa20, chacha20 and chacha20-ietf.
+
The default cipher is 'chacha20-ietf-poly1305'.
+
The '2022-blake3-*' ciphers implement Shadowsocks 2022 (SIP022) and are
the recommended choice: they provide full replay protection and
session-based UDP relay. They require a base64-encoded pre-shared key of
exactly the cipher's key size (16 bytes for 2022-blake3-aes-128-gcm, 32
bytes for the others) given with *-k*; passwords are not accepted and are
never stretched into a key. Generate one with `openssl rand -base64 32`.
+
If built with PolarSSL or custom OpenSSL libraries, some of
these ciphers may not work.

Meanwhile, you configure *shadowsocks-libev* to listen on 0.0.0.0:8388
and bind to eth1. That results the traffic go out through eth1,
but not lo nor eth0. This option is useful to control traffic in
multi-interface environment.

OPTIONS
-------
-s <server_host>::
Set the server's hostname or IP.
// Generated by scripts/gen_cli_docs.py from src/manager.c; do not edit this section.
-k <password>::
Set the password. The server and the client should use the same password.
-m <encrypt_method>::
Set the cipher.
+
*Shadowsocks-libev* accepts 22 different ciphers:
+
2022-blake3-aes-128-gcm, 2022-blake3-aes-256-gcm,
2022-blake3-chacha20-poly1305,

chacha20-ietf-poly1305, xchacha20-ietf-poly1305,
salsa20, chacha20 and chacha20-ietf.
+
The default cipher is 'chacha20-ietf-poly1305'.
+
The '2022-blake3-*' ciphers implement Shadowsocks 2022 (SIP022) and are
the recommended choice: they provide full replay protection and
session-based UDP relay. They require a base64-encoded pre-shared key of
exactly the cipher's key size (16 bytes for 2022-blake3-aes-128-gcm, 32
bytes for the others) given with *-k*; passwords are not accepted and are
never stretched into a key. Generate one with `openssl rand -base64 32`.
+
If built with PolarSSL or custom OpenSSL libraries, some of
these ciphers may not work.
-a <user_name>::
Run as a specific user.
This section lists options across supported builds. Platform and feature
restrictions are noted below; not every option is effective on every platform.
-f <pid_file>::
Start shadowsocks as a daemon with specific pid file.
-s <server_host>::
Set a server listening hostname or IP address. May be repeated.
-l <local_port>::
Accepted for compatibility but ignored by this program; it does not configure a local listener.
-k <password>::
Set the password. The server and the client should use the same password.
-t <timeout>::
Set the socket timeout in seconds. The default value is 60.
-c <config_file>::
Use a configuration file.
-m <encrypt_method>::
Set the cipher. The default is 'chacha20-ietf-poly1305'.
+
You may use "port_password" field inside this configuration file to bring up
multiple ss-server instances together.
AEAD cipher names from the source (availability depends on the build):
aes-128-gcm, aes-192-gcm, aes-256-gcm, 2022-blake3-aes-128-gcm, 2022-blake3-aes-256-gcm, chacha20-ietf-poly1305, 2022-blake3-chacha20-poly1305, xchacha20-ietf-poly1305.
+
Legacy stream cipher names recognized by the source (disabled in minimal builds;
some require backend support): table, rc4, rc4-md5, aes-128-cfb, aes-192-cfb, aes-256-cfb, aes-128-ctr, aes-192-ctr, aes-256-ctr, bf-cfb, camellia-128-cfb, camellia-192-cfb, camellia-256-cfb, cast5-cfb, des-cfb, idea-cfb, rc2-cfb, seed-cfb, salsa20, chacha20, chacha20-ietf.
+
The '2022-blake3-*' ciphers implement Shadowsocks 2022 (SIP022). They require
a base64-encoded pre-shared key supplied with *-k*: 16 bytes for
2022-blake3-aes-128-gcm and 32 bytes for the other 2022 ciphers.
Generate a 32-byte key with `openssl rand -base64 32`.
Passwords are not stretched into keys for these ciphers.
-c <config_file>::
Use a JSON configuration file. The "port_password" field can start multiple ss-server instances.
-i <interface>::
Send traffic through specific network interface.
+
For example, there are three interfaces in your device,
which is lo (127.0.0.1), eth0 (192.168.0.1) and eth1 (192.168.0.2).
Meanwhile, you configure `ss-local` to listen on 0.0.0.0:8388 and bind to eth1.
That results the traffic go out through eth1, but not lo nor eth0.
This option is useful to control traffic in multi-interface environment.
Send outbound traffic through the specified network interface where supported by the platform.
-d <addr>::
Configure name servers for the internal c-ares DNS resolver. By default it uses the system resolver configuration.
-a <user_name>::
Run as a specific user.

2022-blake3-aes-128-gcm and 32 bytes for the other 2022 ciphers.
Generate a 32-byte key with `openssl rand -base64 32`.
Passwords are not stretched into keys for these ciphers.

*Shadowsocks-libev* accepts 22 different ciphers:
+
2022-blake3-aes-128-gcm, 2022-blake3-aes-256-gcm,
2022-blake3-chacha20-poly1305,

chacha20-ietf-poly1305, xchacha20-ietf-poly1305,
salsa20, chacha20 and chacha20-ietf.
+
The default cipher is 'chacha20-ietf-poly1305'.
+
The '2022-blake3-*' ciphers implement Shadowsocks 2022 (SIP022) and are
the recommended choice: they provide full replay protection and
session-based UDP relay. They require a base64-encoded pre-shared key of
exactly the cipher's key size (16 bytes for 2022-blake3-aes-128-gcm, 32
bytes for the others) given with *-k*; passwords are not accepted and are
never stretched into a key. Generate one with `openssl rand -base64 32`.
+
If built with PolarSSL or custom OpenSSL libraries, some of
these ciphers may not work.
-a <user_name>::
Run as a specific user.
-f <pid_file>::
Start shadowsocks as a daemon with specific pid file.
-t <timeout>::
Set the socket timeout in seconds. The default value is 60.
-m <encrypt_method>::

+
Legacy stream cipher names recognized by the source (disabled in minimal builds;
some require backend support): table, rc4, rc4-md5, aes-128-cfb, aes-192-cfb, aes-256-cfb, aes-128-ctr, aes-192-ctr, aes-256-ctr, bf-cfb, camellia-128-cfb, camellia-192-cfb, camellia-256-cfb, cast5-cfb, des-cfb, idea-cfb, rc2-cfb, seed-cfb, salsa20, chacha20, chacha20-ietf.

some require backend support): {cli-stream-ciphers}.
+
The '2022-blake3-*' ciphers implement Shadowsocks 2022 (SIP022). They require
a base64-encoded pre-shared key supplied with *-k*: 16 bytes for
2022-blake3-aes-128-gcm and 32 bytes for the other 2022 ciphers.
Generate a 32-byte key with `openssl rand -base64 32`.
Passwords are not stretched into keys for these ciphers.
-a <user_name>::
Run as a specific user.
-f <pid_file>::
Start shadowsocks as a daemon with specific pid file.
-t <timeout>::
Set the socket timeout in seconds. The default value is 60.
-c <config_file>::
Use a configuration file.
+
Refer to `shadowsocks-c`(8) 'CONFIG FILE' section for more details.
-n <number>::
Specify the maximum number of open files. Requires a platform with setrlimit support.
-i <interface>::
Send outbound traffic through the specified network interface where supported by the platform.
-b <local_address>::
Specify the local address to use while this client is making outbound
connections to the server.
-u::
Enable UDP relay.
-U::
Enable UDP relay and disable TCP relay.
-6::
Resolve hostname to IPv6 address first.
--fast-open::
Enable TCP Fast Open where supported by the operating system.
--reuse-port::
Enable port reuse where supported by the operating system.
--acl <acl_config>::
Enable ACL (Access Control List) and specify config file.
--mtu <MTU>::
Specify the MTU of your network interface.
--mptcp::
Enable Multipath TCP.
+
Only available with MPTCP enabled Linux kernel.
--no-delay::
Enable TCP_NODELAY.
--tcp-incoming-sndbuf <size>::
Set TCP send buffer size for incoming connections.
--tcp-incoming-rcvbuf <size>::
Set TCP receive buffer size for incoming connections.
--tcp-outgoing-sndbuf <size>::
Set TCP send buffer size for outgoing connections.
--tcp-outgoing-rcvbuf <size>::
Set TCP receive buffer size for outgoing connections.
--plugin <plugin_name>::
Enable SIP003 plugin. (Experimental)
--plugin-opts <plugin_options>::
Set SIP003 plugin options. (Experimental)
-v::
Enable verbose mode.
-h::
Print help message.
--help::
Print help message.
-A::
Deprecated one-time authentication option. Exits with an error; use AEAD ciphers instead.
-S <path>::
Android only: UNIX socket path for traffic statistics.
-V::
Android only: enable VPN socket protection.
-L <addr:port>::
Destination server address and port for local port forwarding.
-T::
Use TPROXY instead of REDIRECT for TCP traffic. Requires Linux TPROXY support.
-d <addr>::
Configure name servers for the internal c-ares DNS resolver. By default it uses the system resolver configuration.
-D <path>::
Set the working directory of ss-manager.
--workdir <path>::
Set the working directory of ss-manager (alias for *-D*).
--manager-address <address>::
Set the manager control address: a UNIX domain socket path or an IP address and port.
--executable <path>::
Set the executable path of ss-server used by ss-manager.
--nftables-sets <sets>::
Linux builds with USE_NFTABLES only: add malicious IP addresses to nftables sets. Format: `[<table1>:]<set1>[,[<table2>:]<set2>...]`.
